It may be distributed to on
12、-board electronic devices and systems by conduction or radiation. During recent years, an increasing number of electronic devices have been introduced into vehicle designs in order to perform, for example, control, monitoring and display functions. It has been necessary therefore to consider the ele
13、ctrical and electromagnetic environment in which these devices are required to operate, and, in particular, disturbance generated in the vehicle electrical system itself. This disturbance can cause a temporary malfunction or even permanent damage to the electronic equipment. “Worst case” situations
14、usually result from disturbances generated on the vehicle itself, for example ignition systems, power generating systems, electric motors and controls. While narrow-band signals generated on or outside the vehicle may also affect the performance of electronic devices (broadcasting and radio communic
15、ations transmitters), protection from this potential disturbance has to be considered as part of total system certification; it is outside the scope of this document and is therefore not covered. 1 Scope This part of ISO 7637 defines basic terms used in the various parts for electrical disturbance b
16、y conduction and coupling. It also gives general information relating to the whole International Standard and common to all parts (which are indicated in the Foreword). Parts 1 and 2 consist of test procedures, techniques to improve the electromagnetic compatibility of devices, evaluation of transie
17、nt emissions from disturbance sources, and failure mode severity classification for, respectively, 12 V and 24 V vehicles. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this part of ISO 7637. At the time of publicatio
18、n, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part of ISO 7637 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currentl

IEC 50(151):1978, International Electrotechnical Vocabulary Electrical and magnetic devices. 3 Definitions Definitions of basic terms concerning electromagnetic compatibility are given in IEC 50(151). In addition, for the purposes of this International Standard, the
20、following definitions apply. 3.1 transient Pertaining to or designating a phenomenon or a quantity which varies between two consecutive steady-states during a time interval short compared to the time-scale of interest. 3.1.1 transient duration, td time from the instant when a value rises to 10 % of
